   8# Phase Saturation as the Origin of the Cosmological Constant
   9
  10This module derives the cosmological dark energy fraction
  11Ω_Λ = 11/16 - α/π from the phase saturation of the discrete ledger.
  12
  13## The Core Identification
  14
  15The dark energy fraction Ω_Λ is the equilibrium fraction of the discrete
  16ledger residing in the vacuum state. Phase-saturation pressure on the
  17ledger manifests as vacuum energy at cosmic scales.
  18
  19## The Chain
  20
  211. The ledger has finite phase capacity (saturation scale φ^45)
  222. At cosmic scale, matter excitations and vacuum modes reach equilibrium
  233. The equilibrium vacuum fraction = passive mode fraction from Q₃ geometry
  244. This fraction is 11/16 - α/π ≈ 0.6852

  45The EM correction uses the MEASURED `ExternalAnchors.alpha_CODATA` (2026-07-06
  46revert): within RS the exact value of α is a free boundary datum
  47(`Constants.AlphaGenesis.KappaGammaIrreducibility`), so it enters this formula
